Yeah I was impressed, I did a leakdown and compression test before this season and the motor was healthy. Old temps I would have the coolant pinned after 2 laps. Oil wasn't far behind.

Just a heads up, G series turbos only come in v-band turbine inlet non divided for whatever reason, you welding a different flange on?

Lord. I hoping the ron Davis Rad and twin oil coolers help with temps. I’m going to have mamotorsports do there magic

Another guy I been talking to is going to install a 2 gallon swirl
Pot to see if that helps with heat soaking issues.

Well after the vent work and relocation my coolant issues were non existent with the factory radiator. One thing to note is the 6266 is not water cooled though.
You can see where I moved the oil cooler in this pic, it's just the 30 row that came with the BP kit. Ducting will be your friend combatting temps!

What front bumper is that? Never mind, I found it. It is a Stillen. I thought that is what it was.

I'd like to think part of my engine temps being low is having the BP kit mid mounted (Aside from the aero/venting/relocation) it keeps the hot turbo outside of the engine bay for the most part. Factory manifolds with factory heat shields, Turbo manifold is jet hot coated and wrapped, turbine housing is coated and wrapped with a blanket also.

I'd say the Trackspec vents made the biggest difference though. Do you guys have hood vents?

Oh yes I do. Tracspec as well. They work like a champ.

LOL, I am the one that talked Trackspec into making them. We did the whole group buy thing and tripled the number we needed.

I found it to be worth about 10*. I think the Stillen front bumper does a good job too.

Oh haha, It was so long ago I forgot. Thanks for the push!

I'm actually thinking the openings for the Stillen bumper are too large. I was planning on making the inlet smaller/making the air dam taller and creating partial block off plates for the side inlets ducting it to the intercooler/radiator kinda similar to what Pro Awesome did to their Evo in here.

It is a constant balance of airflow, downforce and cooling. I have been considering some of the same things.

How did it do?

She did well for some DIY tuning and no seat time since last years GTA!

Down somewhere in the neighborhood of 75-100 WHP cause I took a bunch of timing out for the sake of engine safety and still managed to set a new PB!

Wound up getting 4th in Street Class behind Amir & his NSX, A local J32 swapped S2000 and the brand new M4.

Time for a new transmission now though due to a nasty 5th gear grind.
